How to check the integrity of the engine mount and gearbox on a Camry 40

When driving, especially over uneven roads, the engine attachment points to the body are subject to heavy loads.
Rigid fixation of the power unit is unacceptable, otherwise all vibrations will be transmitted to the body.

To maintain comfort and reliable fastening, special support elements are used - engine mounts. They allow the engine to be firmly attached to the body, preventing displacement, and absorb vibrations during operation.

How to replace the lower right engine mount?

1. lift the car;
2. remove the wheel;
3. remove the engine sump protection;
4. Unscrew the lower bolts securing the engine mount;
5. unscrew the upper mounting bolt of the engine mount;
6. place a support under the engine sump;
7. remove the engine mount;
8. compare new and unusable spare parts;
9. install a new engine mount;
10. secure with bolts;
11. perform collection in reverse order.
12. lower the car.

Raise the car on a lift, unscrew the wheel bolts using a pneumatic wrench and a 21 mm hex socket, remove the right wheel;
We unscrew the fastenings of the engine sump protection with a 17 mm socket, remove the protection, use a hydraulic jack;

We find the engine mount and inspect it;

Unscrew the lower bolts securing the engine mount. There are three of them.

Unscrew the mounting bolts using a 17 mm hex head.

Unscrew the upper fastening of the right engine mount. In our work we use a long wrench with a 19 mm hex head;

We place a support under the engine sump. We use a hydraulic jack and two wooden beams so as not to push through the pallet. You can use any other material for the gasket between the jack and the pallet;

We dismantle the unusable part;

We lay out two (old and new) parts on a flat surface, compare them for consistency;

We install a new engine mount and secure it with the upper and lower mounting bolts. We complete the assembly in reverse order and lower the car from the lift.

A year ago I changed everything, installed quattro-freni. At the moment the flight is normal

Hi, I had to replace it twice. Don't buy from China! I press five!

It’s strange, as a rule, the right airbag dies first, it is the most loaded (which is under the timing belt).

I replaced the right one with a new original one (the old one was completely destroyed), I installed the top one with SAT. If I get around to replacing the rest, I’ll install originals from disassembly.

Ps analogues, judging by the reviews of camrivods, it’s a lottery game, for some it’s ok, for others after 30 thousand kilometers everything needs to be changed again.

How can you use the disassembly to determine the mileage that the pillows have covered?

In Moscow time, I found a dismantling shop in the Tula area, judging by the assortment (for example, there are no bumpers with holes for parking sensors and washers), they drag cars from auctions from abroad and saw them, which was confirmed by the seller.

Subjectively: I took the radiator grille and the gas tank neck from them - the condition is close to ideal. I'm looking at their xenon headlights and, by the way, I looked at the pillows

Those. The mileage can only be found out from the seller's words, but I would rely on appearance.

Valery is the seller's name?)

I also took and took a lot of things from him) I’ll have to give him some)

The engine mount is replaced when the part fails. The manufacturer does not limit the service life of the Toyota Camry 2.4 2006 engine mount by regulation. (V40).

Accumulator battery

A low battery can be an unexpected source of vibration. According to reviews, car owners of Toyota Camry 40 with a 2.4-liter engine most often encounter this problem.

The vibration only appears at idle. If you forcefully increase the crankshaft rotation speed using the gas pedal, the unpleasant rattling goes away.

If the battery is faulty, vibration will be especially noticeable as the load on the bot network increases. The reason for this is the high charging current, which the generator is not able to fully provide.

When the battery is dead, the electronics should independently increase the speed, but for a number of reasons this may not happen. In this case, until the battery is replaced or charged, vibration will haunt the car owner when idling.

What is the cost of the right engine mount (hydraulic)

Tools required to perform work on replacing the front lower mount of the Camry 40 2.4 l engine:

1. pneumatic impact wrench;
2. hex head for 17,19 and 21 mm;
3. hydraulic jack;
4. the collar is long;
5. 2 wooden blocks;
6. lift.

Preparing to replace the engine mount

It is better to carry out replacement in warm weather or in a warm room, since the work will have to be done with rubber parts, and as you know, in the cold the rubber becomes hard, and replacement will be difficult. To replace it, it is best to go to the inspection hole.

Next, disconnect the battery to avoid a short circuit. They often start the inspection from the front left side, since it is the easiest to change, and it most often fails.

If the fastening is broken, it can be repaired, since engine mounts cost about 2,000 rubles for a simple foreign car, and about 4,000 rubles for an SUV.

If there is a breakdown in the rubber part of the support, then you definitely need to install new ones. At a service station, such a replacement costs about 300–500 rubles for the front and side airbags, and about 700 rubles for the rear airbag.

How to determine if an engine mount is damaged

It is difficult to immediately understand whether the engine mount has burst or the vibration is transmitted from another part, the road. When starting the engine, vibration will be transmitted and some car enthusiasts sin that the engine has not warmed up, and therefore do not pay attention.

There is a situation when even when the engine is warm, vibration appears and disappears even while driving. When the engine mount is completely out of order, you will hear a characteristic creaking sound of metal on metal.

You can drive to the nearest service station or home with such symptoms, but you should not drive the car, preferably no more than 60 km/h. Often, the rear or left support wears out. You can get a good look at this in the inspection hole, where you can see both the side airbags and the rear one.

If you find a breakdown in one pillow, then get ready that another one will definitely have to be replaced. After the inspection, prepare spare parts for replacement, since you will not be able to drive the car during the replacement.

Toyota Camry engine mount

The model range of this car was produced from 2006 to 2011. Unlike the 50 model, this line is represented by engines with a volume of 2.0 l, 2.4 l, as well as a V-shaped 6-cylinder engine with a volume of 3.5 l. Below we will talk about how to change the front airbag on a Camry.

Main causes of malfunction

If obvious vibration of the body of a Toyota Camry is detected, it is necessary to find out its cause. This is often due to failure of the engine mounts.

A cushion (support, as it is also called) is a rubber-metal product that has several chambers, one of which is hermetically sealed with oil liquid.

The location is similar, for example, to the device in model 50 cars. The design of the machine provides 3 supports:

1. Engine front airbag.
2. Right engine airbag.
3. Left engine airbag.

The Camry has a hydraulic front airbag. The oil poured into the support performs the work according to the damper principle.

The main causes of failure are: rubber delamination and oil leakage.

It is quite easy to determine the malfunction; to do this, you need to drive onto an inspection ditch or overpass and inspect the support. If you find traces of leakage and peeling of rubber, then the engine mount needs to be replaced. Unfortunately, support problems occur quite often in 40 and 50 model cars.

Replacing a Toyota Camry engine mount

If a defect is identified, it is necessary to carry out work to replace the failed part. There is no need to remove the motor to replace the mount. The Camry 40 model front engine mount is designed to secure the front of the engine to the beam. Replacement work will not be difficult. For greater convenience, it is better to place the car on the inspection hole.

First of all, unscrew the engine crankcase protection; for convenience and more space, remove the air filter air intake. Our support is attached with three studs to the beam and one to the internal combustion engine.

If you are an inexperienced specialist, we recommend that you slightly jack up the engine; this is done to prevent the engine from sagging.

However, experienced locksmiths do without this procedure.

Now let's move on to the selection of spare parts, their types and the main features of purchasing the necessary part.

Necessary auto parts

Today, buying auto parts for a Toyota car will not be difficult, since Toyota models have an extensive dealer network throughout the country.

At official Toyota service stations there is a spare parts department where you can easily purchase parts for any model, be it 30, 40 or 50.

The original number of our pillow: 12361-28220.

There are also analogs from various manufacturers: Febest, Fenox, VTR and others. The difference in price is noticeable, approximately twice. Let's figure out which one we should buy. The original product is always of high quality, and its service life is much longer.

Another advantage of the purchase is the warranty on the auto parts. When purchasing alternative options, you are not always provided with a warranty for the auto part, and the product often wears out quite quickly. The quality of workmanship will also differ significantly.

So we advise you to still buy original auto parts.

Bottom line

To summarize, we can say one thing: for long-term and repair-free operation of the car, use only original auto parts. Good luck, and may your car break down less often.

Engines

The engines are very reliable. They have a timing chain drive with a service life of about 250 - 300 thousand km. In rare cases, overheating of the cylinder head of 2.4-liter engines occurs, followed by a change in the geometry of the block.

One of the weak points is the drive belt tensioner, which “ends” after 100,000 km. He gives himself away by “clicking.”

In frosts below 10 degrees, many owners were puzzled when they heard a short “squeak” or metallic grinding sound when starting a cold engine. Its source is the Bendix (overrunning clutch designed to “disengage” the starter from a running engine). The lubricant in the starter freezes, and the “retractor” does not have time to get out. Despite this, starters are quite tenacious. If you want to get rid of the metallic grinding noise in the morning, you need to disassemble the starter and lubricate the sun gear with the Bendix guide splines with a more plastic lubricant.

Often the cooling system pump (pump) also fails prematurely - with a mileage of more than 80 - 100 thousand km. A pink coating and marks on the sound insulation of the hood will tell about his imminent death. The generator pulley may fail after 150 - 200 thousand km.

2.4-liter versions with automatic transmission consume up to 13-15 liters in the city and 7-9 liters on the highway. More powerful 3.5-liter engines are content with 15-16 liters in the city and 9-11 liters on the highway.

The simplest thing. You don’t need to scramble. Look for a clubmate or the same car. Maybe you just have a quirk? and when the second person appears, you can diagnose the airbags with him. To do this, you need to see the reaction of the engine (its roll) when driving or reverse is turned on/off.

How to diagnose engine mounts on a Camry

Checking the performance of engine mounts is very simple, especially if the mount is hydraulic. There are several ways to check the engine mount; it is recommended to use them together for a more accurate diagnosis. To diagnose hydraulic cushions, a visual inspection is most often sufficient. If there are signs of leakage on the pillow or cracks in the body, the pillow must be replaced.

A few more ways to check the supports:

1. On a flat surface, you need to start the engine, open the hood and try to move off without releasing the brake pedal. If the engine moves from its place with characteristic sounds, then the cushion has failed.
2. Open the hood with the engine off and try to move the engine using a pry bar or a piece of pipe. To do this, you need to insert a pry bar between the body and the engine. If the motor shifts significantly or there are extraneous sounds, the pillows need to be replaced.
3. With the engine running, you need to move off in first gear literally a few centimeters. If the cushions are worn, slight jerking will be felt.

To diagnose the lower cushions, you need a lift, jack or inspection hole. With their help, you need to inspect for hydraulic fluid leaks, ruptures or cracks on the engine mounts. Having ruled out the possibility of the car moving, try to shake the engine with a pry bar.

Replacing engine mounts on Camry 40

It is best to replace engine mounts on a lift, if there is one, but if not, you can do it in an inspection pit. It is not recommended to replace it without a hole; in the process of unscrewing the parts, the car may fall off the jack and injure the technician.

The power unit cushions can be dismantled in any order. For this work you will need:

The right upper support is removed from under the hood. The procedure is as follows:

The remaining pillows are changed in the same way.

Advice! After replacing all the cushions, do not immediately tighten the fastenings. You need to start the engine and only then tighten the bolts and nuts.

Engine mount replacement process

1. We remove the protection from the engine to make it easier to reach the necessary parts. First of all, you need to fix the engine with a jack; this can be easily done in the inspection hole by placing a crossbar from a large board so that it supports part of the weight of the engine. This is done so that when you unscrew the support, the engine will sag and there will be nothing to support it.
2. Raising the engine as much as possible so that it is convenient to unscrew the mounting bolts, remove the mount. In the reverse order, we install the new pillow, tighten the bolts well and move on to the rear pillow, this is where the dance with the tambourine begins, since as the car moves, it bears the heaviest load. As a result, not only the fastener itself, which is not the same in shape as the previous ones, bends, but also the fastening bolts are deformed.
3. It will no longer be possible to lift the engine; it is better to tie it to a beam from above or put a crossbar on the glasses and tie the engine to it, having previously lifted it with a jack. Some vehicles will require you to remove pants or other parts that may interfere with replacement. If the fastening bolt is severely deformed, you will have to cut it off with a grinder, otherwise there is no way to unscrew it, some drivers straighten the bolt, but this does not last long, after a while you will have to align it again or replace it with a new one.
4. In order to remove the cushion from its seat, lubricate it with oil or WD-40; often, due to dirt, the cushion can simply rust to the frame. An important point is the installation; on the rear cushion there is a guide, or in other words, an arrow that indicates the direction of movement of the car; it should not be confused, as after a while it may break again. Having assembled everything in reverse order, we move on to the right engine mount. This support also has a problem with deformed bolts, but the main problem is the generator or air conditioning compressor. As we remember, it is not recommended to remove the air conditioning compressor, since as a result of depressurization all the freon will come out, and refilling will cost even more than the airbags and replacement.
5. If you decide to change the engine mounts at a service station, do not be lazy to check the operation of the air conditioner or whether there is pressure in it after repair, since unscrupulous workers, in order to save time, can simply remove the compressor and hide this from you. For most foreign cars, the right airbag is located closer to the right front, so the right headlight and radiator grill are often removed, thus simplifying the replacement procedure.
6. Having made room for removing the cushion, we are faced with the problem of deformation of the bolts; there is no way to cut it with an angle grinder, as it can damage adjacent parts or you simply won’t be able to reach the bolts. I would advise you to take a hacksaw and slowly cut off the bolt; although the procedure is long, it will still not damage the adjacent parts. Having removed the pillow, install a new one in the reverse order; be careful with the radiator, as you can cut your hands on its honeycomb.

Features of replacing engine mounts in a car

How can you tell if your engine mounts need to be replaced?

Without experience, it is very difficult to determine whether the support is worn out or not. Vibration can be transmitted from another part or simply from the road.

Situations also occur when, when starting up the engine, problems that appear are “written off” to the fact that the engine has not yet had time to warm up.

If the component has become completely unusable, passengers will hear a strong creaking of metal that comes from the surfaces rubbing against each other. Let's try to figure out how to properly replace a pillow.

To determine the presence of a worn-out support, you need to drive the car onto an overpass or pit. You will have access to the location of the front and rear airbags. By removing the protection, it will be visually visible that the components have worn out. If a fault is detected in one support, you need to be prepared for the fact that other parts will need to be replaced. After diagnosis, replacement work must begin.

Procedure for installing new cushions

Modern cars can have up to five airbags. Here we are talking about right, left, front, rear, as well as lower and upper, located in the front.

The general principle of replacement is the same everywhere, but it may differ depending on the design features of the vehicle. Initially, you always need to determine how worn the component is.

To determine which components are damaged, you need to remove the accompanying structural elements from the hood.

Once you gain access to the engine mounts, you need to take care of safety. To do this, you need to disconnect the battery terminals. Next, the vehicle is raised using a jack. The algorithm of actions when replacing car engine mounts is as follows:

At first glance, it may seem that this type of work is carried out without any difficulties. Actually this is not true. Only qualified specialists or those people who have already performed the replacement and, accordingly, have understood all the nuances, do not encounter any problems when replacing engine mounts.

If you are not confident in your abilities, then it is better to go to a service station, where the technicians will diagnose the vehicle and replace the component quickly. In addition, the wear of the car engine mount allows the vehicle to be used for a short period of time.

Therefore, at a speed of 60 km/h you can reach the service center.

By treating your car responsibly, you can rest assured that it will work without any problems.

Engine mount

A cushion is a gasket between the engine and body parts. On Soviet-made cars this product looked very simple. This is a durable rubber insert with places for fasteners. Modern power unit support can be of different designs. There are hydraulic cushions and rubber-metal parts. Often, the engine and gearbox on front-wheel drive vehicles are secured using four or five such supports. So, two of them are located under the gearbox, and the rest are under the engine. The rubber-metal support may look different.

Often this is a cylinder made of steel or aluminum, inside of which there is a rubber silent block. There is also a so-called lamp made of aluminum alloys with a rubber insert.

Signs and causes of wear on engine mounts on a Toyota Camry 40

To determine the malfunction, you need to know the functions of the part and the signs of its failure. The Toyota Camry has hydraulic airbags, not simple rubber ones. They dampen vibrations more effectively.

Signs of wear on engine mounts:

• strong vibration on the steering wheel while the engine is running;
• a dull knock at the mounting points of the power unit and gearbox on a rough road;
• jerks and impacts when changing gear at high speeds;
• dull knocks under the hood at idle when starting to drive or switching automatic transmission modes.

Any of these signs requires an inspection of the engine mounts.

Electric motor vibration and methods for eliminating it

Vibration of an electric motor during operation is a fairly common problem, which over time can lead to destruction of the bearings, cracks in the frame and bearing shields, bending of the shaft and separation of the rotor barrel, which ultimately will cause the failure of the electric machine itself. To prevent this, on models used to drive critical mechanisms, an electric motor vibration sensor is installed.

In addition, it is necessary to periodically measure the vibration of the electric motor. For this purpose, a special device is used - a vibration analyzer, which, unlike a vibrograph and vibrometer, not only records the magnitude and amplitude of vibrations, but also allows us to identify their source and cause of occurrence. Measurements are performed at idle and at rated load.

Electric motor vibration: causes

The occurrence of unwanted vibrations can be caused by the influence of both electromagnetic and mechanical factors.

Electromagnetic reasons:

• the appearance of cracks in the rods of the squirrel-cage rotor or their complete breakage;
• deformation of the rotor plates.

A break or crack in at least one rod of the “squirrel cage” is the cause of asymmetry in the magnetic moments acting on the rotor

Due to the deformation of the plates in the active steel, the air gap between the stator and the rotor will be uneven, which will lead to asymmetry of the magnetic fluxes.

Mechanical reasons:

• incorrect alignment of the engine and driven mechanism;
• defects in couplings;
• wear of bearings in the engine or driven mechanism;
• deformation of the electric motor shaft;
• rotor imbalance;
• loosening of fastening at the installation site;
• breakage of welding seams in the console or frame.

Vibration detection algorithm and methods for its elimination

The permissible vibration of the electric motor is determined by the requirements of GOST 16921-71 and GOST 20815-75. If it is not possible to determine its magnitude and causes using special equipment, this simple technique is used.

In normal load mode, it is necessary to inspect the engine and check the reliability of its fastening to the welded structure or foundation anchors and tighten loose threaded connections. After this, the engine is disconnected from the driven mechanism and started in idle mode. If there is no vibration of the electric motor, then the cause of its occurrence is the coupling on the side of the driven mechanism. In this case, check the alignment of the coupling halves, the condition of the rubber washers and petals, as well as the weight of the fingers of one pair (if a discrepancy is detected, fingers with the same weight are selected).

When vibration persists at idle, the cause of its occurrence lies in the engine itself. The source can be identified in the run-down mode of the electric machine (natural stop after the power supply is cut off). If the electric motor stops without shaft runout, it is necessary to check the uniformity of the gap between the rotor and stator. The damped amplitude when the voltage is removed indicates deformation of the rotor shaft, breakage of the short-circuited rods or short circuit of the wound rotor windings.

Rotor imbalance is eliminated on special machines by drilling out excess metal from the end of the shaft. If the phase rotor windings are damaged, they must be rewinded. Cracked and torn squirrel cage rods are removed and replaced with new ones.

The cause of vibration may be worn bearings, which indicate the presence of a defect by increased temperature and loud noise. This type of runout can be eliminated by simply replacing used bearings. Measuring the vibration of motor bearings using installed sensors allows you to identify problems at an early stage.

For critical mechanisms at defense enterprises, hydroelectric power plants, etc., a schedule for measuring vibration of electric motors has been established.
